DEVICE FOR CONTROLLING SHOCK.

Specification of Letters Patent.

Patented Nov. 19, 1918.

Application filed December 11, 1916. Serial No. 136,334.

To all whom it may concern Be it known that I, CHARLES BRYAN BILL-INGHURST, a citizen of the United States, and a resident of Pierre, inthe county of Hughes and State of South Dakota, have invented anImprovement in Devices for Controlling Shock, of which the following isa specification.

My invention is an improvement in devices for controlling shock, and hasfor its object to provide mechanism for use in connection with motorvehicles of every character, for absorbing shock and jar resulting fromthe movement of the vehicle over the road and wherein an improved formof hanger connection is provided for interposition between the body andthe axles of the vehicle.

In the drawings:

Figure 1 is a bottom proved device.

Fig. 2 is a partial rear view of a motor vehicle provided with theimprovement.

Fig. 3 is a partial perspective view of the device looking from below.

The present embodiment of the invention is shown in connection with amotor vehicle, being arranged between the body 1 and the springs 2 whichare mounted on the axles 3. Inner and outer frames 4 and 5 are provided,the said frames being substantially rectangular in outline, and ofchannel material, as shown, the inner frame 4 being arranged with thechannel inward, while the outer frame 5 is arranged with the channeloutward. That is the body portions of the material of the two frames areadjacent.

The outer frame 5 is provided at each side, and near the ends of thesides, with depending standards 6, each standard having at its lower enda pair of laterally spaced inwardly extending lugs 7, and each pair oflugs is connected by a pin 8. The inner frai e 4 is provided rt each endwith a pair of similar standar s J. the said standards 9 being?' nearthe ends of the ends. and each sizzndam 9 ii p:'o" dcd at its lower endwith :i'pair of outwardly facing laterally spaced lugs 10. crcIi pair oflugs being connected by a pin 11. Adjacent each standard 6 the innerframe is provided with a pair of lugs 12. and cccb hair of lugs 12 isconnected by plan view of the ima crors pin 13. Adjacent to eachstandard 0 the outer fr me 5 is provided with a pair of dependin lugs14.:1nd each H'UX ot lug: is connc .ed by v. cz'css pm 13. 'lhe pins 15are directly above the pins 11 and the pins 13 are directly above thepins 8, and each pair of pins 813 and 11-14, is connected by a hanger 16and 17, respectively of flexible non-elastic material, as, for instance,leather.

In the present instance, each of these hang ers is composed of a loopengaging the pins, the intermediate portions of the loops being securedtogether by rivets or the like. The inner frame 4 is connected with thebody 1 in any suitable or desired manner, and the outer frame 5 isconnected with the springs 2 shown. Thus the inner frame and the bodyare suspended from the outer frame and the springs by non-metallicflexible.

hangers, which interrupt any vibrations transmitted from the outer tothe mner frame. Both frames are cushioned against the road by thesprings and the tires, so that a minimum of shock and jar is transmittedto the body.

In the drawings the flexible hangers are shown to be attached at theends of the frames, but it is obvious that attachments could bemade atdifferent parts of the frames; for instance, the pendants 9 and hangers17 could be attached to the side members of the frame midway between theends thereof, and the pendants 6 and hangers 16 could be attached to theends of the frame.

As is known, all shock and vibration work upward from road contact, andgo first to the ends of the outer frame, because the springs areattached at or near the ends. If there is a rigid metallic connection,between the body of the vehicle and the outer frame, these vibrationsare directly transferred from the outer frame to the body. In thepresent construction, however, this direct metallic connection is brokenor interruotcd by CITSTQ IEQ between the body and the frame liex'blnon-metallic connection". It is obviom that any shock making compressionin he direction of the length of he (tn-metall c connection would beabrorbcd ly the sa d conne tion. The same is true with checks and jarslateral to the lfi,Qi,l1 of the said connection. The only thock or iarhat cculd by any possibility be tran fer ed dirc th would be those oftcrsoa in the length of the connection, and practice shows that theerhocks are lessened and for the greater part eliminated. The straps donot :1 t a: cushions, but as interstantially "rectangula't frames, theinner frame being adapted to support the body, and the outer frame beingadapted to be connected with the springs of the vehicle and I a flexiblenoi' -metallic connectionbetween the inner and the a outer frames forsup porting saidinner frame near the level of the outer frame, saidconnection comprising depending hangers on the frames and straps offlexible non-metallic .material between the hanger and th other frame.

2., A device for controlling shock in m0'- tor vehicles comprising innerand outer substantially rectangular frames, the inner framebeing adaptedto support the body, and the outer frame being adapted to be connectedwith the springs of the vehicle, and a flexible non-metallic connectionbetween the inner and the outer framesfor supporting said inner framenear the level of the outer frame, said connection comprising a pair ofdepending. standards at each side of theouter frame and at each end oftheinner frame, and a flexible non-metallic strap con necting eachstandard to the adj acent frame.

3. Adevice for controlling shock in motor vehicles comprising inner orouter substantially rectangular frames, the inner framebeingadapted, tosupport the body, and the outer frame being adapted to be connectedwith-the springs of the vehicle, and a flexible non-metallic connectionbeixes-e11nie inner and outer frames for supporting said inner framenear the level of the outer frame, saidconnection comprising one or moredepending standards at each side ofthe outer frame and at each end ofthe inner frame, and a flexible non-metallic strap connecting eachstandard to the adjacent frame. i

4. Means for controlling shock in motor vehicles, comprising inner andouter frames, one of said frames being adapted tosupport a body and theother being adapted for connection with the springs, depending hangersat the sides andends of the frames, the

hangers at the ends: being on one frame and the hangers at the sides onthe other frame, and flexible non-metallic connections between thehangers and the otherframe.

H 5.. In amotor vehicle, means for controlling shock, comprising anon-metallic flexible' connection between. the body and the springs,said connection comprising supporting members for the body and othermembers for limiting the upward movement of the body with respect to thesprings.
